Implement a sortable grid correctly

[hungify]

Hello there!
pragmatic-reorder.netlify.app

Here’s a simpler version: Repo, but there are some flicker UI issues to address.

What’s the correct way to handle this situation? If anyone has any suggestions, I’d love to hear them! Thank you!

Drive-by comment (was checking the issues while implementing the package).

I had some strange behaviour in React when I didn't return the cleanup function returned from functions such as combine(), monitorForElements(), dropTargetForElements(). Not too familiar with Vue but I imagine it functions similarly.

Issue 1: The onDropTargetChange event executes unnecessarily multiple times.

1. Event Flow:
   • When you drag Item A to the position of Item B, the onDropTargetChange event fires and performs a reorder list
   • After reordering, Items A and B swapped places, but the library detected that their positions had changed relative to each other.
   • Re-trigger enters and leaves events again (A “leaves” B and then “enters” its new position; similarly for B).
2. Consequence:
   • The onDropTargetChange event fires again after the list has already been reordered.
